TsoLay Textile Color Fastness Test Gray Card, Grey Scale for Staining Assessment, 5 Levels 9 Gears Color Fastness, Used to Evaluate Discolouration and Colour Transfer in Colourfastness Testing

Specifications: Function: Textile color fastness test Color: 5 levels, 9 gears Note: The gray sample card will change during storage or use and the chromaticity data of each grade will deviate from the standard range. Pay attention to regular verification and replacement. Otherwise it will affect the accuracy of the assessment. Application: This gray card is suitable for the color fastness rating of textiles in GB, ISO, AATCC, DIN, BS, JIS, EN standards. Precautions for use: 1. Keep the gray card clean. 2. Always check the gray card for fingerprints. 3. If the imprint has been found to interfere with the rating, the gray card must be replaced. 4. Try to avoid mechanical damage caused by touch. 5. If mechanical damage interferes with the rating, it should be replaced. 6. After the gray card is used up, put it into the sleeve.

• This series of gray cards is an international 5-level 9-speed specification type. The gray card grayscale is completely made of ISO, AATCC, GB colorimetric data, and is carefully color-matched. Divided into 1-5 grades, half-level increment.
• This gray card is suitable for the color fastness rating of textiles in GB, ISO, AATCC, DIN, BS, JIS, EN standards. This Textile Color Card is used to evaluate Staining in color fastness test.
• Durable & Professional-Grade: Designed for long-term use with high-quality materials, ensuring stable performance in laboratory or industrial settings for consistent color fastness testing.
• Note: Never touch the nine pairs of gray or white cards in the sample card when using. If the small card is found to be fluffed, scratched, damaged, or stained with water, stains, or stains, stop using it. Stop using the sample card when it is distorted, skewed, or uneven.
• Application: The gray scale for evaluating color change is not only suitable for determining the color fastness of textiles, but also can be used to determine the color fastness of any object during processing and application.
